Qooltek Adjustable Foam Cannon 1L for Karcher K2-K7 Pressure Washer

Excellent product, I did my research and wondered if a foam cannon would be worth it. I bought this one and love it, Easy to use, connects perfectly and dose not leak, cleans better than the old wash/go. spray adjustment is ideal would highly recommend this product.

Excellent foam cannon and great performance ⭐⭐⭐⭐⭐ The Qooltek Adjustable Foam Cannon (1 L) works perfectly with my Karcher pressure washer and makes car washing so much easier. It produces thick, rich snow foam that clings to the paintwork really well, helping lift dirt before you even touch the sponge. The adjustable nozzle and foam output give you good control, and the bottle feels sturdy and well‑made. Easy to attach and clean, and saves loads of time on prep and rinsing. Definitely a great addition to any car care setup — very happy with it!

Does exactly what it’s designed for. Excellent foam and easy to use. Would be 5 stars if…. Bottle had a metal screw thread as it’s a bit tricky to correctly screw it into the brass fitting without cross threading it. I’m going to add a metal adapter onto the bottle to prevent this from happening. Would be useful to have some level marking on the side of the bottle to make it easier to fill with solution and water in the correct mixture. The + - knob to adjust the water to foam mix has become stuck with the black plastic knob just turning without adjusting the mix. Will have to repair it to get it to work properly again.

I bought this item as a replacement for my Karcher K2, my original snow foam gun was directly from Karcher and broke within 3 months. This one is far superior for less cost. It's easy to use, the scale on the side of the bottle makes it easy to get the ratio's perfect and it gave me the best clean I've had yet Adjusting the jet and power of the foam was simple and it was perfectly compatible with my K2 and was a lot easier to fit compared to the actual Karcher ones. This is the best foam gun I've bought so far

The Qooltek Adjustable Foam Cannon works perfectly with my Karcher K7 jetwash to create thick, consistent snow foam. Setup is straightforward, and the adjustable nozzle allows precise control over the foam density. Build quality is excellent - the metal components feel solid and durable. It handles repeated use without leaks or issues, and the foam coverage is impressive for both cars and larger surfaces (I’ve used it on my caravan too) At this point, I haven’t noticed any downsides and I’ve been using it for a few months now, it’s well-made, efficient, and doesn’t feel heavy when in use.

Great item works well would definitely recommend.

Can be difficult to connect to lance. Not a 100% fit. Also the bottle broke afer a few months of use, so its no longer useable. I wonder if bottle can be replaced separately???

Great Snow foam cannon well worth the money

Lo uso para lavar autos

Very good

Was für eine Wirkung! Ein riesiger Unterschied zu meinen bisherigen Erfahrungen mit Schaumkanonen. Diese Schaumkanone ist wirklich gut. Direkt an den Hochdruckreiniger aus dem Schwabenland angeschlossen und mit Autoreinigungsschaum befüllt. Beim ersten Einsatz war ich direkt total begeistert. Man kann die Spraymenge und die breite des Strahles einstellen. Mit einer Füllung konnte ich 2 Autos komplett einschäumen. Zwischenzeitlich nutze ich das Gerät auch für Wohnwagen und Fahrräder. Zusätzlich lässt sich das Teil leicht reinigen und schnell wieder einsatzbereit machen. Fazit: es wird keine Kaufreue geben - also kaufen!

Ottimo funzionale

it worked once and then it broke…
